In recent years, with the rapid development of the Internet and communication technology, online learning has become an important means and way for college students to acquire knowledge, but the quality and effect of online learning are not satisfactory. By exploring the reasons why college students are willing to invest time and energy in online learning, more targeted online courses can be developed to further promote the overall knowledge literacy of college students. This article adopts a data-driven approach, starting from the emotional dimension, by studying the comments and barrage data of some courses in bilibili, China University MOOC, and Tencent classrooms, after data cleaning, use topic analysis, word cloud graphs and data visualization to analyze the emotional state of college students in the process of learning online classes. Combined with the interactive mode, manipulation method, and auxiliary functions of the online course, leads to the reasons why college students are willing to invest time and energy in online learning. Through the research results, we found that online teaching videos with advanced marking of the difficulty of the course, humorous teaching style, and high degree of interaction are more popular among college students. Therefore, this research suggests that teachers can carry out gradient teaching when recording online courses, breaking down the difficulties from simple to deep, from easy to difficult, and at the same time increase teacher-student interaction in the teaching process to increase students' participation, thereby increasing the emotional investment in online learning level. Applying the findings of this survey to online teaching platforms and online teaching arrangements for colleges and universities will better increase the degree of college students' online learning investment, and improve the sustainability of college students' online learning investment as a whole.
